11 Claims. (Cl. 221-23) This invention relates to iiuid dispensing means and more particularly to a means for dispensing oil or other liquids. from an initially concealed can.

An object of this invention is to provide a liquid dispensing means including a holder for a sealed liquid can, means for piercing the can at the top and bottom thereof, and means for connecting the piercing means with an air pressure line.

Another object of the invention is to provide a dispensing means of this type which is adapted to enclose a sealed can, the device including a means for piercing the can so as to permit the contents thereof to readily iiow out of the can and also includes a liquid dispensing nozzle or pipe.

A further object of this invention is to provide, in a liquid dispensing means, an improved device for puncturing one end of the oil can when mounted in the holder so as to provide an air vent, the vent puncturing means being operated simultaneously with a piercing means engaging the opposite ends of the can so as to provide an outlet for the liquid.

A still further object of this invention is to provide in a structure of this kind a holder which is adapted to entirely enclose the oil can, the holder including a. pair of puncturing members which are adapted to engage the can through the upper and lower end of the holder.

Embodying the aims aforesaid and to others which may hereinafter appear, the invention consists of the novel construction, combination, and arrangement of parts as will be more specifically referred to and as illustrated in the accompanying drawing, wherein are shown embodiments of the invention, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the scope of the invention, as

claimed.

Figure 1 is a vertical section, partly in detail, of a liquid dispensing means constructed. according to an embodiment of this invention;

Figure 2 is a fragmentary top plan of the device, partly broken away and in section; and

Figure 3 isan enlarged fragmentary vertical section, showing the vent producing means carried by the upper portion of the device.

Referring to the drawing, the numeral I3 designates generally a hollow base structure which, in the present instance, is constructed of substantially frustro-conical configuration, being provided at the base thereof with an inwardly projecting flange I3. An upper ange Il is formed at the upper end of the base member I0. A cylindrical body l2, provided with a lower bottom I4,

is secured by means of fastening devices l5 to the base I0. The cylindrical member I2 is provided at the upper end thereof with the closure or lid I6 which is hingedly secured to the body I2 by 5 means of a hinge structure I1.

The body I2, at a point upwardly from the lower en'd thereof, is provided with an inner bottom I3, and a partition I9 extends diametrically across r the body I2, being secured to the inner bottom 10 IB and the lower bottom I4 thereby dividing the i space between the lower bottom I4, and the inner bottom I8 into a delivery chamber 20, and a sec ond chamber 2|. The space above the inner bottom I8 forms a 'can receiving chamber 22. 15 within which a sealed oil can 23 .is adapted to removably engage. A spring 24 is disposed in the receptacle chamber 22, one end of the spring 24 engaging the upper surface of the inner bottom I8, and the other end of the spring24 engag.. 20 l v ing against the bottom 25 of the can 23.

The body I2 adjacent the lower end thereof, is provided with an outwardly olset portion 26 and a nipple 21 extends outwardly from the extension 26. One end of a exible delivery tube or nozzle 25l 28, is secured, as by fastening members 29, within the nipple 21. A bottom puncturing blade 3U is disposed within the delivery chamber 20, and is constructed in substantially annular form and with an outer side 3l substantially longer than the 30 inner side 32 in order to provide a relatively sharp blade structure which is adapted to initially pierce the bottom 25 of the can and then roll the straight portion.thereof inwardly of the can 23.

The blade is carried by a stem 33 which is 35 v fastening means 40, and is slidable within the 5 cylinder 35. A fixed bottom wall 4I is disposed at the lower end of the cylinder 35, and one end of an air pressure pipe 42 is connected to the cylinder adjacent the bottom 4I, and below the plunger or piston 39. Y A spring 43 is disposed 50 within the cylinder 35 about the stem 33, and

one end of the spring 43 engages against the inner f end of the piston or plunger 35 while the other l end of the spring 43 engages against the guide member 33, The cylinder 35, at a point adjacent and slightly below the guide member 38. is provided with a vent 44 so as to permit the air above the plunger 39 to exhaust into the atmosphere. A vertically disposed handle 45 is secured to the body I2, by means of an arm 46 and a second arm or extension 41. 'Ihe handle 45 is provided with a bore 48 extending vertically therethrough, and a valve plug 49 is slidable in the lower p0rtion of the bore 48. The valve stem 50 is secured to the plug 49 and extends upwardly through the bore 48. A knob or operating member 5I, having a boss 52, is secured to the upper end of the stem 50. The boss 52 is of a diameter such that it is adapted to slidably engage in the upper end of the bore 48. A spring 53 is disposed in the bore 48 and at one end bears against the lower end of the boss 52. The opposite end of the spring 53 bears against a shoulder or seat 54 provided in the bore 48 below the upper end thereof. The valve plug 49 is provided with a fluid passage 55 which is adapted to connect an inlet port 56 with an outlet port 51 formed in a valve housing 58 below the handle supporting member 41. In the present instance the bore 48 opens through the lower end of the valve housing 58 thereby forming an exhaust port 59 so that when the valve plug 49 is in a port closing position across the inner end of the intake port 56 the outlet port 51 will communicate with the exhaust port 59. A flexible hose 60 is adapted to be secured to a nipple 6I by a coupling means 62 and the hose 60 is adapted to be connected to a suitable source of air or other uid pressure supply. A can piercing blade 63 is carried by a-right angularly disposed supporting arm 64 which is integral with an elongated stem 65. 'I'he blade 63, when in operative position, is adapted to slidably engage through an opening 66 which is formed in the closure I6 adjacent the margin thereof, opposite from the hinge I1. 'Ihe closure I6 is adapted to be releasably held in closed position on the upper end of the body I2 by means of a latch 61 which is secured by fastening means 68 to the body I2 adjacent the upper end thereof. The latch 61 is resilient and is provided with a cam-shaped bill 69 which is adapted to be engaged by the marginal edge of the lid or closure 6 I, and to be moved outwardly by pressure against the lid 6 I, so as to permit the lid 6I to engage between the bill 69 and the upper end of the body I2. A second cylinder 18 is disposed laterally of the body I2, being mounted on the supporting member 41. 'Ihe cylinder 10 is provided with a head 1I having a stem guiding boss 12. A plunger or piston 13 is slidable in the cylinder 10 and is normally urged upwardly to an upper blade released position by means of a spring 'I4 which at one end engages against the plunger 13 and at the opposite end engages against the bottom wall 15. A vent 16 is formed through the wall of the cylinder 10, adjacent the bottom wall 15, so that air in the cylinder 10 below the plunger 13, can readily be exhausted. An air pipe 11 is connected at one end to the cylinder 10 adjacent the head 1I, and at the other end is connected to a T or coupling 18 which is connected to the pipe 42. In this manner movement of the valve plug 49 to an open position will communicate the intake port 56 with the outlet port 51 so that air, under pressure, will pass through the pipe 42 into the cylinder 35 below the plunger 39 and will also pass through the pipe 11 into the cylinder 10 above the plunger 13.

In order to provide a means whereby the blade 63 may be moved to a released position so as to permit the ready movement of the lid I6 to an open position, I have provided a spiral groove 19 in the stem 65. The stem 65 is slidable through the arm 46 which forms a guide means for the stem 65 at the upper portion of the body I2, and a pin or threaded key engages through the guide arm 46 and engages in the groove 19 so that longitudinal movement oi the stem 65 will be accompanied by rotary movement thereof. This rotary movement is substantially one-half turn, as shown in Figure 1, so that when in inoperative position, which is the position shown in full lines in Figure 1, the blade 63 will be disposed diametrically opposite to the operating position, which is the position shown in dotted lines. The stem 65, adjacent the upper end thereof, is provided with a resilient latch holding member 8I, which is adapted to engage against the latch 61 when the blade 63 is in operative position. It will be noted from Figure 1, that the spiral groove 19 communicates at its upper end with a straight, longitudinal groove 82, so that the stem 65, after being swung from inoperative position to an operative position may have endwise movement unaccompanied by rotary movement.

In use and operation of this dispensing device the air hose 60 is adapted to be connected to a. suitable source of air pressure means. The oil can 23 is initially mounted in the holder or body I2, and a lid I6 then closed and latched by a latching member 61. 'I'he knob 5I may then be pressed downwardly, by the thumb or the like, so as to communicate the intake port 56 with the outlet 51. In this position the port 55, in the plug 49, will communicate with the two ports 56 and 51. I'he air under pressure will pass through the pipe 42 into the lower end of the cylinder 35 so as to thereby force the plunger 39 upwardly against the tension of the spring 43. The bottom piercing blade 30 will puncture the bottom wall 25 of the can so that the oil or other liquid in the can may then flow into the discharge chamber 20. At the same time that air under pressure is forcing the plunger 39 upwardly air under pressure will pass through the pipe 11 into the cylinder 10 above the plunger 13 so as to move the plunger 13 downwardly. The downward movement of the plunger 13 will cause the stem 65 to be initially rotated substantially one-half turn so as to bring the blade 63 in alignment with the opening 68 in the lid I6. Further downward movement of the stem 65 will cause the key 80 to engage in the straight groove 82 so as to hold the blade 63 against rotary movement. 'Ihe opening 66 in the lid I 6 constitutes a guide means for the vent blade 63. Thus blade 63 will then puncture an opening in the top wall 83 of the can 23. The knob 5I may then be released so as to permit the spring 53 to move the valve plug 49 to a closed position across the inner end of the intake port 56. At this time the outlet port 51 communicates with the exhaust port 59 so that the spring 43 may move the plunger 39 downwardly and at the same time the spring 14 may move the plunger 13 upwardly. 'I'he ilexible discharge hose 28 may then be released from the resilient clamp 84 which is secured to the upper portion of the holder I2, and the liquid from the can 23 then discharged through the discharge opening 85 formed in the bottom wall I8.
